Bright Side of News delivers some details about the GeForce GTX 465, the third Fermi graphics card that should arrive within a week or two. Seems like the card has a GPU with 352 shaders clocked at 1215MHz, GPU clockspeed of 607MHz and 1GB GDDR5 clocked at 3204MHz. Interestingly, the card is longer than the GeForce GTX 470, but shorter than the GeForce GTX 480, and it's expected to have a significantly lower TDP than the GTX 470.
Pricing is expected to be around $249 (269EUR).
GeForce GTX 465 will feature an GF100 chip with five SM blocks fused of - thus, 352 cores are clocked at 1,215 MHz i.e. identical clock to the one on GTX 470 cards. The rest of GPU will tick at 607MHz [1,215.33MHz /2 = 607.66 MHz]. The GPU will connect to no less than eight GDDR5 chips for a grand total of 1,024MB of video memory, using a 256-bit memory controller [128-bits i.e. four memory controllers are fused off].
Given that the clock of memory is decreased to 801MHz QDR, i.e. identical to Tesla and Quadro
, these 3.206 billion transfers per second [GT/s, "GHz" - we won't go into GDDR vs. GQDR, what GDDR5 actually is] result in memory bandwidth
of 102.6GB/s. When compared to elderly brothers, that is a 30% deficit to GTX 470 and a 75% deficit to GTX 480.
